STANDARD DETAILS AND SPECIFICATIONS
March 1995

The purpose of Engineering Design Standards and Specifications is to provide minimum standards for the design, methods of construction, kinds and uses of materials, and the preparation of plans for construction, repair or alteration of streets, roadways, concrete structures, drainage, sewerage and water supply facilities within the City of Paso Robles, where any portion of such improvement is to be maintained or operated by the City. Any items which are not included in these Standards or Specifications shall be constructed in accordance with California State Standard Specifications or Green Book as defined below, or if not covered in the State Standard Specifications or Green Book as approved by the City Engineer. In case of a conflict, the more restrictive shall apply.

The textual portions of the Standards and Specifications are available for viewing and download beginning with Section I below. Standard Drawing sheets are available individually in pdf format. Click here to jump to the listing of drawings.
